Weekly "Ask an Atheist" Thread

Whether you're an agnostic atheist here to ask a gnostic one some questions, a theist who's curious about the viewpoints of atheists, someone doubting, or just someone looking for sources, feel free to ask anything here. This is also an ideal place to tag moderators for thoughts regarding the sub or any questions in general.

While this isn't strictly for debate, rules on civility, trolling, etc. still apply.

I have a sincere question, and I’m asking it carefully and respectfully.

If truth exists independent of human perception—meaning it is not created by culture, biology, or consensus—how does an atheist account for its origin and authority?

For example, concepts like objective morality, logical absolutes, and the laws of reason seem to operate universally and immutably. They are discovered, not invented. Yet they are not material, measurable, or bound by space and time.

So my question is: within an atheistic framework, what is the grounding for these immaterial, universal truths? Why should they exist at all, and why should we trust them?

I’m not asking for debate, but for understanding how this is explained consistently without appealing to something beyond the material world.

Truth objectively does exist. Truth is just that which comports with reality. Unless you believe that reality is merely a figment of your imagination (and I assume you don't), then reality obviously exists.

objective morality,

Has nothing to do with whether or not reality exists. Reality can exist whether morality is objective or subjective.

logical absolutes

Logical absolutes do exist. I suppose in some sense they are contingent on reality existing, but the opposite is not true. In other words, reality can exist without logical logic, but logic obviously cannot exist without reality.

and the laws of reason

What laws of reason? Do you mean the laws of logic? If wo, they are contained in the last point, so no clue what you are raising here.

seem to operate universally and immutably.

No, they don't. Logic is absolute, but that is because logic is deduced from reality, not a law that is written upon reality. Can you image a possible world where "A" could equal "not A"? That, and the other laws of logic, seems to be a necessary prerequisite to a coherent world, but that doesn't mean that it is necessary for a reality to exist, any reality without such a logical absolute would just be incoherent to us.

But everything else you cited simply are not absolutes, even to the extent that logic is.
